Acer Aspire 5230 no post screen

Hi to all, today i have turn on my notebook and nothing happend
The notebook simply turn on, i can hear the fan, i see the power on led, but the monitor is just blank, even if i try to connect the notebook to an external monitor i can see nothing.

So i have disassembled the pc, changed the bios battery, changed the thermal compound, cleaned everything but nothing happened.

I have also tried to power on the lapton without the ram, and there wasn't "bios beep". So i suspected some kind of bios corruption.

I have tried to flash the bios via crysis disk, with an usb pen drive, but nothing happened. The only "good news" is that the optical drive blink, and seems to try to read something

This is what i read in the lapton stickers:

Aspire 5230
Model No: JAWD0

What can i do? There is a way to flash the bios via optical drive? Anyone have a suggestion?. When the last night i turned off the laptop all was ok

Thanks for the answers and sorry for my poor english

Hi!

 

I don't see why it would be BIOS corruption - it doesn't just happen on its own for no reason.
It sounds more like a motherboard failure for me.

 

This is what also i suspected, but i have seen many asus one affected by this same issue, and it was some sort of bios bug. So my "hopes" was to try to reflash te bios with a new versione and see what happened.

Do you have other suggestion?

Thanks for your help.

Hi!

 

My guess - use a heat gun or a hair dryer on a chipset (both Northbridge and Southbridge) and press them into the board and then try to start it up quickly (without assembling it fully).
I've seen that happen I the past on old laptops - chipset is somehow glued to the mobo and it separates in time with each heat up and could down cycle.
If my experiment works - it surely is a mobo issue and you would know exactly which part is to blame.

You should also test the notebook without the battery and with the batty but without AC.

 

I have tried to heat up both chipset but no result. I have also tested the notebook with and without the battery but nothing change.

Any other suggestion, or i have to put it into the trash?

Hi!

 

I have nothing more right now. Maybe someone else has something to suggest we haven't thought of.
